The sawmill industry is vital for Ghana’s economic development but faces challenges in energy efficiency. This study evaluates energy consumption patterns in the Sunyani Municipality’s sawmill industry to identify cost‑saving opportunities. Adopting a census approach, the study surveyed all nine operational sawmills using self‑administered questionnaires and walkthrough energy audits based on ASHRAE standards. The analysis revealed a significant lack of structured energy management; most facilities do not monitor con-sumption or adjust to price changes. Technical assessments identified inefficiencies, notably power factors below 0.9 in seven sawmills and the widespread use of inefficient lighting. While total energy consumption decreased between 2021 and 2022, total electricity costs increased, highlighting the financial impact of these inefficiencies and rising tariffs. The study concludes that the industry misses critical opportunities for cost optimization. Recommendations include the installation of power factor correction banks, retrofitting with LED lighting, and implementing employee training programs. These measures are essential for enhancing profitability and ensuring industrial sustainability in Ghana’s forestry sector.
